A New 3D Watermarking Algorithm

In this paper, an original spatial watermarking technique adapted for 3D images is presented. This technique lowers the computational complexity that normally rises with the traditional watermarking algorithms. This new algorithm produces an invisible watermark that is robust to various kinds of attacks. The technique uses a slice-based approach to 3D watermarking. The proposed technique modifies pixels of the 3D object by a spatial watermark insertion. Spatial mask of suitable size is used to hide data with less visual impairments.
